Perhaps you should try some spelling variations:
presentada » presentado, presented, presentar, presenteda
presentan » presente, present, presentacion, presenten
presentacione » presentaciones, presentacionde, presentacion, presentecione
presentados » presentado, presentadas, presentaron, presentedos
presentaban » presentaron, presentadas, presentacion, presenteban
presenta » presente

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((presentada OR presentan) OR (((presentacione OR presentados) OR presentaban) OR presenta))~".
• Adding a wildcard symbol may retrieve word variants: ((presentada OR presentan) OR (((presentacione OR presentados) OR presentaban) OR presenta))*.
